APPARATUS FOR MAKING SHEET-METAL BOXES.

SPECIFICATION-forming partof Letters Patent No. 625,872, dated May 30 ,1899.

Application filed April 1c .1898,

To all whom i2; may concern:

Be it known that I, Trro LIvIo CARBONE,

a citizen of Italy, residing at No. 343 Calle for making these boxes, as will be described,

referring to the accompanying drawings, in which Figure 1 shows a plan and an edge view of the blank or piece of metal from which the box-body is shaped. Fig. 2 shows a plan and an edge View of the box-lid, the'plan looking at its outside. Fig. 3 shows a plan and an edge View of the box-lid, the plan looking at its inside. Fig. 4 shows a plan and. an edge view' of the box-body formed or shaped from the blank, Fig.1, except that the back flap has not been fully curved. Fig. 5 shows a plan and an edge view like Fig. 4, the back flap being fully curved. Fig. 6 shows a plan and an edge view ofthe box with the boxlid open, prior tobending up the'front'wall of the box-body. 4 Fig.7 shows a plan and an edge View of the completed boi ,:the lid being open. Fig. 8 is a part elevation and part sec tion of the press employed forshaping the box and applying the lid. Fig. 9 is a plan of the base of the press, part of which is shown to cessive positions of the parts for applying the lid to the box; Fig. 23 is a side view of the levers for moving the slide for feeding the lids. Figs. 24 and 25 are sections on plans at right angles to each other of the dies for Serial a. 677,860. on model.

shapingthe lids. Fig. 26 is a plan. 1 Fig. 27 is a part section and Fig. 28. a part plan on an enlarged scale. Fig. 29 is an eulargedview of the punch and springs for detaching the lid.

The apparatus, which will presently bedescribed, is constructed and arranged so as to carry a box and its lid through the successive stages of manufacture shownby Figs, 1 to 7,

inclusive. Fig. 1 shows the pieceaof sheet metal cut out to form the body of the box.

Fig. 2 shows the piece I) for the lid, which is simplydished a little, as shown in Fig. 3. The box-bodyis also dished, the back llap being curved, as shown in Fig. 4. This flap .is bent farther forward, as shown in Fig. 5.

The lid is then placed with its edge lying in the groove of the back flap, as shown in Fig. (3, the sides of the box being nowturned up. Finally, as shown in Fig. ,7, the front of the box is turned up and the two upper lips of the sides are bent over the two tongues of the lids, so as to constitute a spring-hinge.

The shaping of the box-body and the plac ing of the lid are effected bya press such as b to have been prepared as will hereinafter be described, the plates at are piled on the press anism. I

The feeding mechanism for the plates a comprises an eccentric or cam on. the flywheel shaft of the press, which at every revolution moves to and fro a lever z', which terminates in a fork engaging pins t" on a sliding frame f, having a pair of inclined studs f projecting just the thickness of one of the plates at, so that as f makes its stroke to the right it pushes the lowest plate a to the first die 0, where on the descent of the punch m it receives its first dishing, and on the retreat of the punch it is pushed upward by the bottom of the die, which is urged upward by a spring g. At each side of the slide 1 there is ICO a bar f which'is fixed to fand moves with it,

so that when the dishedpiece a is pushed up out of the die it is advanced'by the bars f to nose n and has mounted on it a spring-finger t in the form of a yoke, having in its middle a nose t, which being guided along a camguide 01 operates in conjunction with the nose n to turn over the rounded back of the box and to secure the lid bin position, these lids being fed in the following manner: An arm 0 Fig. 23,.attached to the vertically-reciprocating head 0, which carries the punches m andn by means of levers r 0", gives reciproeating movement to a feed-slide 0", Figs. 13, 14, 15, and 16, which slides over a plate 19, having through it an inclined slot 12. The slide 9" has atongue r and an adjustable nose 0*, which as it moves to the left along with the tongue 7" pushes the lowest lid 1') onward, causingit to drop through the slot 1 as shown in Figs. 16 and 17.

Referring now to Figs. 17 to 22, inclusive, the lid 12 is received on an inclined guide 41 down which it descends while the punch n descends, and while the die is bending the back of the box over the nose n, Fig. 19, the edge of the lid 1), guided by the nose I? of the pawl 2, descends into the groove formed along the front edge of the box-back, Fig. 20. Then by the farther descent of the punch or. and box to the position shown in Fig. 21 the box ends, the lips of which had been previously turned vertically upward, are made by the sides of the die to turn upward, and consequently their lips are closed over the tongues of the -lid, completing the hinge. The punch 91 then rising, the bottom of the die, urged upward by the spring g, pushes up the completed box a, with its lid 1), in upright position, as shown in Fig. 22, and the dished plate for the succeeding box as it is fed forward pushes the finished box off the punch and its nose, so that it drops into a bent tube m, which conducts to a receptacle below.

The separate apparatus for feeding and dishing the lids 1) (shown in Figs. 24, to 29, inclusive) is similarto that for effecting the feed and first dishing of the plates at. A feed-slide F, with adjustable sloping projections F, is moved forward by a forked lever I, worked by a cam or eccentric on the shaft of the press, pushing the lowest of the pile of plates 1) under the punch M, which descends while the slide F is retracted by spring-levers K. As the punch M rises a pair of springs S holds back the dished lid 1), which at the next advance of the feed-slide is pushed by the side bars F onto an incline, down which it slides. The dished lids are then taken to the press, Fig. 8, where they are piled between the columns 0, as shown in Fig. 13.

I claim in respect of apparatus for making sheet-metal boxes 1. The combination in a press for making boxes, of two punches, one in advance of the other, a revolving fiy-wheel shaft which works the punches, the two dies, arranged one in advance of the other, and cooperating respectively with the two punches to first dish the box-blank by one punch and die and fin ish the subsequent folding or bending operations by means of the second punch or die, and feed mechanism for successively feeding the box-blanks to the first die and punch, substantially as described.

2. The combination in a press for makingboxes, of twopunches, one in advance of the other, a revolving fly-wheel shaft which works the punches, the two dies, arranged one in advance of the other, and cooperating respectively with the two punches to first dish the box-blank by one punch and die and finish the subsequent folding or bending operations by means of the second punch or die, feed mechanism for successively feeding the box-blanks to the first die and punch, and box-lid feeding and guiding mechanism for successively feeding the box-lids to the' boxbodies which are being operated upon by the second die and punch, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
